walking/throwing belts! whats going on?
hey guys, i've been beating myself up trying to find the problem, or cure for the belt issue i've been having.
first of all, it an 05 GTO, with a few mods on the pulley system. I have an underdrive crank, and i'm looking for an overdrive alt. when i get on it a bit, i have to pop my hood just to make sure it's still on streight; it likes to walk over a groove or 2 on the tensioner pulley. this in turn pulls it slightly off the water pump pully, and gets it out of line on the power steering a groove or 2.
with this beeing said, i have bought a new tensioner, and a new belt (el cheap-o till i get this fixed). *edit* there are 3 indicators on the tensioner, i'm lined up at the tightest one.*edit* i have considered getting a tensioner pulley machined with higher edges on it, as to "guide" the belt a little better, but i think this might just mask some other problem.
also i have checked the water pump (nice and solid), the power steering has no side to side motion. alt is good, almost looks new, free spins nice and easy. the idler is slightly loose, but i can't see that cuasing anything since it don't jump or walk off the crank UD pulley.
what do you think?
